To foster national resilience, the United States needs advanced experimental capabilities that can support research in understanding and reducing human, infrastructure, and property losses from extreme wind and wind-water events, particularly hurricanes. Recent windstorms have demonstrated rapid intensification where wind gusts have exceeded 200 miles per hour (mph), and there are indications that the number of very high intensity windstorms will increase in the coming years. To mitigate the impact of extreme wind and wind-water events on the built environment, a university-based research and testing facility is needed that can simulate wind fields reaching 200 mph. This award will support an engineering workshop to identify research infrastructure concepts for a national, full-scale, 200 mph wind and wind-water testing facility capable of supporting research and testing beyond the wind speeds and scales that are achievable with current testing facilities in the United States. Additionally, because storm surge (wind-driven water) is the principal life safety threat in hurricanes, the workshop will identify ways to integrate storm surge and wave actions into the facility design. The long-term goal of the workshop is to advance wind engineering research with new testing capabilities that can enhance the hurricane resilience of the built environment. This workshop supports the National Science Foundation's role in the National Windstorm Impact Reduction Program. The workshop report will be disseminated to the natural hazards and engineering research communities via the Natural Hazards Engineering Research Infrastructure (NHERI) Data Depot (https://www.DesignSafe-ci.org). The two-day workshop will be held virtually in August 2020 due to the ongoing COVID-19 pandemic. The workshop will identify conceptual gaps in existing mid-scale research infrastructure (MsRI) and assess the feasibility and design options for a national, full-scale, 200 mph wind and wind-water testing facility. The workshop, hosted by Florida International University, will include 50 participants from research and engineering applications communities from universities, businesses, professional associations, and government. The workshop will include design and construction conceptualization of a unique MsRI to (a) advance knowledge on the characterization of the transient nature of wind-surge-wave combined hazards, and (b) enable robust simulations of the behavior of civil infrastructure under the multi-stressor environment of hurricane landfalls. The workshop will include a project management expert and a conference facilitator to work with plenary leaders and breakout session chairs. The outcome of the workshop will be a report that will identify the research needs and a conceptual design for the facility.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

为了增强国家的恢复能力，美国需要先进的实验能力，以支持研究，以了解和减少极端风和风雨事件，特别是飓风造成的人员、基础设施和财产损失。最近的风暴已经显示出快速增强，风速超过每小时200英里（每小时200英里），并且有迹象表明，在未来几年，非常高强度的风暴的数量将会增加。为了减轻极端风和风-水事件对建筑环境的影响，需要一个基于大学的研究和测试设施，可以模拟达到200英里/小时的风场。该奖项将支持一个工程研讨会，以确定研究基础设施概念，以建立一个全国性的、全尺寸的、时速200英里的风和风-水测试设施，该设施能够支持美国现有测试设施所能达到的风速和规模之外的研究和测试。此外，由于风暴潮（风力驱动的水）是飓风中主要的生命安全威胁，研讨会将确定将风暴潮和波浪作用纳入设施设计的方法。研讨会的长期目标是通过新的测试能力来推进风力工程研究，从而提高建筑环境的飓风恢复能力。本次研讨会支持国家科学基金会在国家减少风暴影响计划中的作用。讲习班报告将通过自然灾害工程研究基础设施（NHERI）数据库（https://www.DesignSafe-ci.org）分发给自然灾害和工程研究界。由于新冠肺炎疫情持续，为期两天的研讨会将于2020年8月以虚拟方式举行。该研讨会将确定现有中等规模研究基础设施（MsRI）的概念差距，并评估国家规模、时速200英里的风力和风力水测试设施的可行性和设计方案。该研讨会由佛罗里达国际大学主办，将有50名来自大学、企业、专业协会和政府的研究和工程应用社区的参与者。该研讨会将包括一个独特的MsRI的设计和建造概念化，以(a)提高对风浪联合危害的瞬态特性的认识，以及(b)在飓风登陆的多应力源环境下对民用基础设施行为的强大模拟。讲习班将包括一名项目管理专家和一名会议主持人，与全体会议领导人和分组会议主席一起工作。讲习班的结果将是一份报告，其中将确定研究需要和该设施的概念设计。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
